Famous quotes containing the words current and/or positive:
“Phlebas the Phoenician, a fortnight dead,
Forgot the cry of gulls, and the deep sea swell
And the profit and loss.
A current under sea
Picked his bones in whispers. As he rose and fell
He passed the stages of his age and youth
Entering the whirlpool.”
—T.S. (Thomas Stearns)
“The oaks, how subtle and marine!
Bearded, and all the layered light
Above them swims; and thus the scene,
Recessed, awaits the positive night.”
—Robert Penn Warren (19051989)
